Extinctions on the rise in the Galapagos: overfishing and global warming devastating islands' species =0
The Problem!!! Several species of marine plants and animals are believed to have become extinct and many others are seriously threatened, a new report reveals. Researchers blame the impact of rising ocean temperatures coupled with fishing and tourism. Once abundant coral reefs and kelp beds had been wiped out in just a few decades, said the scientists from US-based Conservation International. Species that were previously plentiful such as the Galapagos black-spotted damselfish, the 24-rayed sunstar and the Galapagos stringweed were now thought to have vanished. Dozens of others, including the Galapagos penguin, were within ''a hairsbreadth of annihilation''.
The Potential Consequences =[
The wildlife we eat today was part of an ecosystem which was under stress from global climate change and when these ecosystems are damaged, alot of species can vanish.
Climate changes will increase the erosion of coral reefs.
Many species are now known as vulnerable due to over fishing.
Expansion of sea urchin populations has upset the delicate web of marine life in the islands.
Which is causing them to consume more algea at high rates. Algea is VERY! important for other marine species.
The Solution =D
Catch share programs replace complex rules dictating how fishing will be practiced
Fishermen, individually or in cooperatives, are granted a percentage share of the total allowable catch. They can also be granted exclusive access to particular fishing zones.
As long as fishermen do not exceed their share, they have greater flexibility to fish when weather and market conditions are best.
$$$$$$$The economy$$$$$$
As the fisherman shares grow in value as the overall fishery improves, providing them a greater financial stake in sound resource management.
The economy can manage the amount of fish that people take.
